Periodic solutions of fourth-order delay differential equation
In this paper the periodic solutions of fourth order delay differential equation of the form $ddddot{x}(t)+adddot{x}(t)+f(ddot{x}(t-tau(t)))+g(dot{x}(t-tau(t)))+h({x}(t-tau(t)))=p(t)$ is investigated. Some new positive periodic criteria are given.

متن کاملNew Result in the Ultimate Boundedness of Solutions of a Third-order Nonlinear Ordinary Differential Equation
Sufficient conditions are established for the ultimate boundedness of solutions of certain third-order nonlinear differential equations. Our result improves on Tunc’s [C. Tunc, Boundedness of solutions of a third-order nonlinear differential equation, J. Inequal. Pure and Appl. Math., 6(1) Art. 3,2005,1-6].
متن کاملOn the Periodic Solutions of a Certain Nonlinear Vector Differential Equation of Fourth-order
Our aim is essentially to establish a theorem which contains sufficient conditions that guarantee the non-existence of nontrivial periodic solutions of a certain nonlinear vector differential equation of fourth order.
